These are the most amazing buckings ive ever used... hands down no questions asked. If youre looking to get superior range this is the bucking you need. Do not however... the lighter the bb the more sensitive the hop adjustments become as the rubber can start to over hop the rounds... In pistols... .25g bbs recommended... but it still sends .2s on a accurate and straight trajectory downrange once you fine tune the adjustment wheel. Hope this was useful. Cheers
